    my stihls exhaust screens clog up with that black nasty gunk when the weather gets good and hot. (We have 100+ degree summers) I have learned to just take the screens off, they run better. Some say they are "spark arrestors" and they are a fire hazard if you remove them, but I have never had any fires started from doing this.

    My dealer sold me some of this. Going to give it a shot.

    Keep in mind it isn't a miracle product so you need to clean up the engine before expecting the product to do it. I ran it over teh winter and one
    thing I like about it is the dark red which you can see in bbright sun. Kinda nice to pour a little out on gnd to be sure if the tank has oil.
